Note a) The following are true for computer nodes (i.e., computers with a

Controller Link Support Board mounted).

•The data link starting position is fixed.

•Because areas such as bit-access areas and the DM Area are not sup- ported, areas must be made available on the computer for linking.

•Automatically set data links cannot be started from the Controller Link Support Board.

•The Controller Link Support Board can participate in automatically set data links.

b)If data links are manually set, send/receive area can be selected in each node, allowing send/receive groups to be created within the network in area 1 and area 2, as shown below.
